Obvious proviso out of the way: this is not intended to be a like for like comparison, and by being is based only on visits to OMG! Ubuntu! is not likely indicative of wider trends with browsers on Linux, or elsewhere.

But stats are always interesting, and with almost 80% of our millions of monthly visitors using Linux, it’s fun to spot trends and notice usage patterns.

In the graph above, which only shows Uk visits made using Chrome and Firefox, it’s evident that the late March release of Firefox 4 boosted Mozilla’s market share amongst our Linux visitors. The change is rather dramatic during March, with an almost instantaneous leap-frog in usage coming at the expense of Chrome.

But what about world wide? Is the trend the same for all vistors to OMG! Ubuntu!? That answer is yes: –

With Mozilla’s increased release cycle it will be interesting to note if the ‘novelty’ of new Firefox releases wears off, and whether subsequent releases of Chrome can stir the same kind of frenzied fickleness that Firefox 4 brought.
